I am trying to model Saturn's moon Pandora, since high resolution images have been released from a Cassini flyby a few months ago. Does anyone have experience with programs that would let me map a partial texture of the surface to a model? I have some experience with Blender, but its mostly been modeling without texturing. I'm just bad at visualizing how Blender's UV editing system works.

The Celestia utility cmodview is purported to be able to import obj format and export it to cmod, obviating the need to use special export scripts in your favorite 3D design program (including Blender or Anim8or) since most modeling programs can export to obj format (which includes both meshes and surface texture maps).

I have to write "purported" because cmodview doesn't work at all on my computer
